Specification of Letters Patent. Patgnted June 251), 1915,

Application filed March 20, 1915. Serial No. 15,866.

To all whom it may concern Be it known that I, EDWARD L. DELANY,residing at and whose post-office address is 828 Kent avenue, Borough ofBrooklyn of the city of New York, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in ValveDevices; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

I provide simple and efl'ective means for holding a flush tank valveopen while the water is passing through the spud, the holding meansbeing rendered effective by the flow of the water to contact with thevalve and hold it by frictional engagement, and release the valve andallow it to seat when the flow of water ceases.

In the accompanying drawing the figure shows a tank valve partly in sideelevation and partly broken away to show the catch device. I

The casing 1, adapted for attachment to a flush tank, is shown providedwith an overflow tube 2 on which is mounted a laterally projecting arm 3having an aperture in its extremity constituting a guide for the operating rod 4, by which the valve 5 is lifted from its seat. This arm alsoconstitutes a stop for the valve when the latter is being elevated.

6 is the valve seat which may be of any preferred form.

Within the casing, and preferably cast therewith, I have shown a bracket7 having an aperture 8 adapted to constitute a guide for the valve stem9. This stem extends downward from the valve, through the aperture andinto the spud. The stem is shown with its lower extremity tapered as at10. When the valve is unseated to the extent allowed by the arm 3, thetapered portion of the stem is partly within and partly above theaperture 8 in the bracket, as shown in dotted lines, so that a forceacting laterally on the stem will cause the valve to be held elevated bythe frictional engagement of the tapered extremity with the wall of theaperture, the bracket acting as a catch or stop. To create this lateralforce and effect the shift of the stem, I have shown a gravitating spoonshaped member 12. This is shown formed with ears 13 fulcrumed on thebracket and with a lateral top portion 14 having an aperture thereinthrough which the valve stem extends. This spoon element, when the valveis seated or the tank is empty, hangs by gravity so that it will notinterfere with the movement of the valve. It is substantially straightand extends down into the spud approximately parallel with the stem.W'hen, however, the valve is unseated and the tapered portion of thestem is within the aperture in the bracket, the flowing column of waterswings the gravitating spoon member and causes its top 14; to shift thevalve stem so that the latter is held by positive engagement with thebracket 7. When the flow of water ceases and the spoon member releasesthe stem, the latter is free to drop and as it is, throughout its lengthabove the extremity, of substantially the diameter of the aperture 8,the valve will be evenly guided to its seat.

I claim as my invention 1. Ina valve device, the combination with avertically movable valve having a depend ing stem, a catch for saidstem, a gravitating lever fulcrumed in proximity to said catch andformed with an .aperture through which said stem passes and adapted tobe actuated by the flow of water to shift said valve stem intoengagement with said catch to hold said valve unseated.

2. In a valve device, the combination with a vertically movable, valvehaving a depending stem formed with a tapered extremity, a

guide through which said stem extends, a stop limiting the upwardmovement of said valve, a gravitating lever adapted to be actuated bythe flow of water and having a spoon at its lower extremity and disposedsubstantially parallel to said stem, and adapted to bear against saidstem when the valve is unseated and hold the tapered extremity of saidstem in frictional engage ment with said guide.

3. In a valve device, a valve having a depending stem tapered at itslower extremity,

a bracket having an aperture constituting a guide for said stem, a stopto limit the unseating movement of said valve, and a gravitating'leverfulcrumed on said bracket and having a lateral top portion formed withan aperture to receive said stem, said lever bespecification in thepresence of two subscribmg adapted to be actuated by the flow of ingWitnesses.
